HTC
has a string of hits on its hands when it comes to Android-based
smartphones. The Droid Incredible, which was introduced back in early
June, is still hard to come by due to component shortages and
Verizon's website says that new stock won't
come in until August 9.

It
now appears that another HTC phone is being held back by component
shortages: the Sprint's EVO 4G. According to the Wall
Street Journal,
the main holdup in EVO 4G production comes from the Samsung
touchscreens that are used on the smartphone. To make matters worse,
Samsung won't have additional production capacity for touchscreens
until its new factory is completed in 2012.

Whereas
Verizon has a date set in stone for when it will receive additional
stock of Droid Incredible smartphones, Sprint simply states
on its site:

Sorry,
this device is so hot we can’t keep it on our virtual shelves.

The
EVO 4G is the first smartphone available to U.S. customers with 4G
connectivity. Sprint is also currently the only major wireless
provider in the United States to offer limited 4G connectivity

but larger rivals Verizon and AT&T are quickly moving to ready
their competing networks.

"We
thought we would have more of a head start than we'll end up having,"
said Sprint CEO Dan Hesse.
